Air conditioner



April 27, 1937. w. BONNER AIR CONDITIONER Filed Feb. 8, 1936 M/QBonfier Patented Apr. 27, 1937 PATENT OFFICE AIR CONDITIONER v Willis Bonner, Duncan, Okla. Application February a, 1936, Serial No. 62,999

' I 6 Claims; 261-92) Thisinvention relates to air conditioners or moisteners whereby fresh moist air may be discharged into a room.

' The'general object of the invention is to provide an air conditioner of this type in which a fan is used for the purpose of spraying the water into the air, and another fan used for discharging the air into the room, the first one ofthese fans being operated by the normal passage of air from the exterior of the room into the interior of theroom. V

Another'object is to provide a structure of this character in the form of a box or casing of any suitable character having an inlet opening at one end and an outlet opening at the other, and provided with a water receptacle in its bottom, and the provision of a fan adjacent the air inlet opening and operated by the air passing through this opening, which fan dips into the water, and 20 as it rotates, discharges a spray into the air of the casing, and the provision of a second fan at the outlet opening of the character also operated by the normal current of air and which acts to propel the air into the room.

Other objects will appear'in the course of the following description.

My invention is illustrated in the accompanying drawing wherelm- Figure 1 is a longitudinal section through a conditioner constructed according to my invention;

Figure 2 is a section on the line 2--2 of F gure 1;

Figure 3 is a face view of the woven or water absorbent baille.

Referring to this drawing, casing which may have any suitable length, height or width, and which is provided with an inlet opening I I at its rear end, an outlet opening l2 at its forward end, and a pipe l3 of any desired length leading from this outlet opening; The lower portion of the casing is formed to provide a water tank or receptacle ll. Supported in suitable bearing brackets I5 is an air propelled fan I6, the blades of which dip into the water. This fan is rotated by the natural flow of air through the opening Ii to the opening l2. Between the opening l2 and the fan are disposed one or more baflies mounted upon screen frames l1 and preferably these baflles include a sheet of line wire netting and a sheet of woven material having large interspaces between the threads, as shown in Figure 3. Disposed forward of the opening l2 within the pipe or outlet I3 is a second fan l8 which is motor driven. This fan is mounted it designates a screened by relatively coarse wire netting having a A" mesh or a mesh or even greater mesh. The wire cloth or netting on the screen I! is designated 2|, while the relatively coarsely woven fabric is designated 22. This, as shown in Figure 3, is formed of yarn, thread or the like, woven so coarsely as to leave ample space between the threads 'for the circulation of air. This fabric 22 absorbs moisture and carries it up by capillary. attraction into the path of the air stream. Preferably a coarse wire netting designated 23 extends across the opening I 2. The screen wire 22 is used for preventing the water from misting into the room. The number of baiiies I1 and the placing of these baffles depends on the powerofthe motor and general conditions of the room where the air conditioner is located. Thus if the air conditioner is placed in a store where space is small and damage would be caused by moisture, it would be necessary to hold all the water in check from passing into the room though the woven baflles 22 would moisten the air. If there were plenty of room, fewer baflies would be used.

The casing may be of any desired length, as before stated, and may be made small enough to be disposed within a window opening or large enough to be used for air conditioning a relatively large area. Where the natural flow of air is strong, the fan l8 may be omitted as this natural flow of air, .under these circumstances, will cause the rotation of the fan !6, which will cause a spray of water into the air and the moistening of the air even if very few or no baflies are used. On the other hand, if the natural flow of air is not strong enough, it is necessary to provide the fan l8 which will positively draw the air through the casing l0 and eject it into the room.

I- do not wish to be, limited to the exact form of the casing nor the \proportions illustrated as obviously these might be varied in many ways without departing from the spirit. of the invention as defined in the claims.

What is claimed is:-

1. An air conditioner of the character de- ,scribed, comprising a casing, means for retainthe upper portion of the casing, a power operated fan located at the discharge opening of the easing, and a baflie of permeable material interposed between the fans and partitioning the easing from and above the surface of the water therein.

2. An air conditioner of the character described, comprising a casing, means for retaining water in the lower portion of the casing, the casing having an inlet opening at one end and a discharge opening at the other, a fan the blades of which dip at their tips only into the water of the casing, the fan when rotated acting to throw water into the upper portion of the casing, a power operated fan located at the discharge opening of the casing, and a woven material baffle located between the first fan and the discharge opening and in such proximity to the first fan as to have the water drawn against the bafile as it is thrown from the blades.

3. An air conditioner of the character described, comprising a casing, the lower portion of which is formed to hold water, the casing having an inlet opening at one end and a discharge opening at the other, a fan disposed adjacent the inlet opening, the blades of which dip into the water of the casing, a power operated fan located at the discharge opening of the casing and bailies depending from the top of the casing and extending into the water, each of said bafiies comprising a sheet of fine wire netting, and a spaced sheet of coarsely woven; textile fabric, the fabric having relatively large interspaces between the threads through which air may readily pass.

4. An air conditioner of the character described comprising a casing, means for retaining water in the lower portion of the casing, the casing having an inlet opening at one end and a discharge opening at the other end, a fan the blades of which dip at their tips only into the water in the lower portion of the casing, the fan when rotated acting to throw water .into the upper portion of the casing, a power operated fan located at the discharge opening of the casing, and a baiile forming a partition in the casing and disposed between the fans and in relatively close proximity to the first mentioned fan and comprising two spaced parallel fabricated sheets, one of said sheets being in the nature of relatively closely woven wire and the other of the sheets being in the nature of a woven textile material of absorbent character and having its lower edge immersed in the water.

5. An air conditioner of the character described, comprising a casing, means for retaining water in the lower portion of the casing, the casing having an inlet opening at one end and a discharge opening at the other, a fan, the blades of which dip into the water of the casing, the fan acting to throw water from the blade tips into the upper portion of the casing, a power operated fan located at the discharge opening of the casing, and a bafile wall of woven permeable material between the fans and completely partitioning the casing from the top of and above the water therein.

6. An air conditioner of the character described, comprising a casing, means for retaining water in the lower portion of the casing, the casing having an inlet opening at one end and a discharge opening at the other, a fan, the blades of which dip into the water of the casing, the fanacting to throw water from the blade tips into the upper portion of the casing, a power operated fan'located at the discharge opening of the easing, and a bafiie wall between the fans and comprising a woven permeable body-and a body of fibrous material overlying a side of the first body.
